About Rahul Jain
I am a Staff / Principal‑level Software Engineer with 18 years of hands‑on experience building ultra–low‑latency, cloud‑native platforms for global financial‑services firms. My career spans the full spectrum of distributed‑systems engineering— from writing lock‑free Java code that meets sub‑millisecond p99 latency targets to steering multi‑region Kubernetes deployments that deliver 99.99 % uptime.What I’ve delivered • Sub‑millisecond market‑making platform used across three continents, processing 500 k+ ticks/sec with < 1 ms p99 latency. • Cloud migration of a legacy risk‑analytics stack to Azure Kubernetes Service, cutting infrastructure spend by 27 % and enabling zero‑downtime releases via GitOps. • Real‑time data lake on KDB+ and Kafka Streams that slashed analytics query times from minutes to seconds and unlocked new ML trading models. • DevOps & SRE uplift—instituted Terraform‑based IaC, observability with Prometheus / Grafana, and chaos‑testing pipelines, driving mean‑time‑to‑recovery down by 65 %.Core competenciesJava / Spring Boot • KDB+/ q • Kafka / Kafka Streams • Reactive Microservices • Kubernetes & Helm • Azure & Terraform • Low‑latency performance tuning • Event‑driven architectures • CI/CD & GitOps • SRE & Observability • Technical leadership & mentoringWhy I’m hereI thrive on transforming complex, high‑throughput systems into resilient, elegantly scalable products—and mentoring teams to do the same. I’m now exploring opportunities where my blend of deep technical craft, execution discipline, and cross‑team leadership can accelerate innovation in trading, fintech, or any domain that demands real‑time, mission‑critical software.
